Hi Blacburn, thanks for your reply, apreciate it a lot.

What i wanna make is a plasma cnc cutter really, ive read router should be stronger , about toothed belts, if you have some pictures about how are sliders and pulleys, i was checking for motors and controler parts, not sure if this will works good:

CNC Systems

also they sell pulleys belts too. what i wanna see is about sliders or the system about router moves..that's my concern right now.

Thanks again!
